Operating Procedures
3.8 – Turning on AC Input Circuit Breaker
With the ac line cord plugged in and the dc cable
connected to the TI200-PFC, push the ac rocker switch
to the “On” position. After approximately 5-8 seconds,
the unit’s LED status indicator will illuminate indicating
output power status, and cooling fans will operate. When
the TI200-PFC is operational the system will recondition
and recharge vehicle batteries, power avionics, and any
additional ground support.
Low Power Demand
Low power demand is defined by a requirement of 200 amps or less. If the load demand is less than 200
amps, converter output will remain at 28.5 Vdc (only one GREEN LED status indicator bar will illuminate).
If load demand exceeds 200 amps converter voltage output will decrease and two or more LED status
indicator bars will illuminate.
High Power Demand
High power demand is defined by a requirement of greater than 200 amps. Connect to aircraft ground power
receptacle. DC bus power should come on and aircraft voltmeter should indicate 28.5 Vdc to 23.5 Vdc (23
Vdc minimum). If current demand is greater than 200 amps, converter output voltage will drop below 28.0
Vdc and LED status indicator lights will illuminate indicating current is being drawn from the power cells.
The greater the current draw, the quicker the LED status indicator will approach red. Note the LED status
indicator shows the status of the power cells.
3.9 – Removing DC Power Supply From Vehicle or Aircraft
Turn Off AC Input Circuit Breaker.
1.
Remove dc power cable GPU connector from vehicle or aircraft. Follow the Installation Instructions in
2.
reverse.
Remove dc power cable connector from TI200-PFC (if necessary). Follow the Installation Instructions in
3.
reverse.
Reinstall dc receptacle’s protective cover.
4.
Unplug ac line cord from the wall by twisting the plug a quarter turn counter-clockwise then pull out of
5.
the receptacle.
